Contraindications

A contraindication is a medical condition or factor that makes the use of a specific medication unsafe. If you have any of the following conditions, Solriamfetol may not be appropriate for you. Always consult your healthcare provider before starting any new medication, including Solriamfetol.

Uncontrolled High Blood Pressure (Hypertension): Solriamfetol can increase blood pressure, which may exacerbate uncontrolled hypertension and lead to serious complications.

Heart Disease: Individuals with a history of heart conditions, such as heart attacks, angina, or irregular heart rhythms (arrhythmias), may face a heightened risk of cardiovascular issues when taking Solriamfetol.

History of Stroke: Because Solriamfetol can raise blood pressure, it may increase the likelihood of another stroke in individuals with a prior history of cerebrovascular events.

Severe Anxiety or Agitation: Due to its stimulant effects, Solriamfetol may worsen symptoms of anxiety or agitation, making it unsuitable for individuals with these conditions.

Monoamine Oxidase Inhibitors (MAOIs): Taking Solriamfetol while using MAOIs or within 14 days of discontinuing them can result in dangerously high blood pressure levels.

Drug-to-Drug Interactions

Solriamfetol may interact with other medications, potentially causing harmful side effects or reducing its effectiveness. It is essential to inform your healthcare provider about all medications you are taking, including over-the-counter drugs and supplements. Known interactions include:

Monoamine Oxidase Inhibitors (MAOIs) (e.g., Nardil [phenelzine], Parnate [tranylcypromine]): Combining Solriamfetol with MAOIs can lead to dangerously elevated blood pressure, posing a serious health risk.

Other Stimulants (e.g., Adderall [amphetamine/dextroamphetamine], Ritalin [methylphenidate]): Using Solriamfetol alongside other stimulants may amplify side effects such as increased heart rate, elevated blood pressure, and heightened anxiety.

Antidepressants (e.g., Zoloft [sertraline], Prozac [fluoxetine]): Certain antidepressants may interact with Solriamfetol, increasing the risk of serotonin syndrome—a potentially serious condition caused by excessive serotonin levels in the brain.

Blood Pressure Medications (e.g., Lisinopril, Amlodipine): Solriamfetol may reduce the effectiveness of blood pressure medications, potentially leading to uncontrolled hypertension.

Solriamfetol in Pregnancy

Is it safe to take Solriamfetol during pregnancy?

The safety of Solriamfetol during pregnancy has not been well established. Limited data is available regarding its effects on pregnant women and their unborn children. While animal studies suggest potential risks, it is unclear whether these findings apply to humans. If you are pregnant or planning to become pregnant, consult your healthcare provider to carefully weigh the potential risks and benefits of using Solriamfetol. Your provider will help determine the most appropriate course of action for your individual circumstances.

Solriamfetol while Breastfeeding

Is it safe to take Solriamfetol while breastfeeding?

There is currently insufficient data to determine whether Solriamfetol passes into breast milk or its potential effects on a nursing infant. Due to this lack of information, caution is advised when considering Solriamfetol while breastfeeding. Discuss with your healthcare provider whether the benefits of taking Solriamfetol outweigh any potential risks to your baby. If you are breastfeeding and require treatment for conditions such as narcolepsy or sleep apnea, your provider may suggest alternative options.

Estimated Cost of Solriamfetol Medication

The cost of a 30-day supply of Solriamfetol (75 mg or 150 mg) without insurance typically ranges from $600 to $700 when using a GoodRx coupon. Prices may vary depending on the pharmacy and location, so it is advisable to check for updated pricing before making a purchase. If affordability is a concern, speak with your healthcare provider about alternative treatments or assistance programs that may be available to help reduce costs.

Possible Alternatives to Solriamfetol

If Solriamfetol is not suitable for you or if you are exploring other treatment options, several alternatives are available. Always consult your healthcare provider before making any changes to your treatment plan. Telemedicine providers can also assist in evaluating these alternatives.

Narcolepsy: Medications such as Modafinil (Provigil) or Armodafinil (Nuvigil) are commonly prescribed for narcolepsy. Additionally, lifestyle changes, such as maintaining a consistent sleep schedule and incorporating short daytime naps, may help manage symptoms.

Obstructive Sleep Apnea: Continuous Positive Airway Pressure (CPAP) therapy is the standard treatment for sleep apnea. Other options may include weight loss, positional therapy, or, in certain cases, surgical interventions.

Excessive Daytime Sleepiness: In addition to medications like Solriamfetol or Modafinil, improving sleep hygiene, reducing caffeine intake, and addressing underlying sleep disorders can help alleviate daytime sleepiness.

Insomnia: Cognitive Behavioral Therapy for Insomnia (CBT-I) is a highly effective, non-pharmacological treatment. Short-term use of medications such as Zolpidem (Ambien) or Eszopiclone (Lunesta) may also be considered under medical supervision.

Sleep Disorders: Treatment varies depending on the specific disorder and may include medications, lifestyle adjustments, or therapies such as CBT-I or CPAP for sleep apnea.

Hypersomnia: Medications like Modafinil or Armodafinil are often prescribed for hypersomnia. Ensuring adequate sleep and addressing underlying conditions, such as depression or sleep apnea, are also essential components of treatment.

Chronic Fatigue Syndrome: While there is no definitive cure, treatment focuses on symptom management through graded exercise therapy, cognitive behavioral therapy, and medications for pain or sleep disturbances.

Attention Deficit Hyperactivity Disorder (ADHD): Stimulant medications such as Adderall (amphetamine/dextroamphetamine) or Ritalin (methylphenidate) are commonly prescribed. Behavioral therapy and lifestyle changes, such as improving organizational skills and minimizing distractions, can also be beneficial.

Depression: Antidepressants like Sertraline (Zoloft) or Fluoxetine (Prozac) are frequently prescribed. Therapy, such as Cognitive Behavioral Therapy (CBT), and lifestyle modifications, including regular exercise and a balanced diet, may also support recovery.

Anxiety: Medications such as Escitalopram (Lexapro) or Alprazolam (Xanax) may be prescribed for anxiety. Therapy, particularly CBT, and relaxation techniques like mindfulness and meditation can also help manage symptoms effectively.

Recent Updates on Solriamfetol Research

Recent studies on Solriamfetol have provided valuable insights into its long-term safety and effectiveness, particularly for managing excessive daytime sleepiness associated with narcolepsy and obstructive sleep apnea. A pivotal 2022 study demonstrated that Solriamfetol effectively sustained wakefulness over a 52-week period. Furthermore, the study reaffirmed that its safety profile aligns with findings from earlier short-term research, offering reassurance about its continued use.

In addition to its approved uses, researchers are investigating potential applications of Solriamfetol for conditions such as hypersomnia and chronic fatigue syndrome. While preliminary findings in these areas are promising, further research is needed to fully understand the drug’s broader therapeutic potential and to confirm its efficacy in these contexts.
